SPECIFICATION forming part of Letters Patent No. 288,203, dated November13, 1883.

\ Application filed April 9, 1883. (No model.)

To a/Z whom it may concern:

Beit known that we, THoims BEADWELL and SAM. K. WHITE, citizens of theUnited States, residing at Chicago, in the 'county of specication.

Cool: and State of Illinois, have jointly invented new and usefulImprovements in Stereotyping Outiits, of which the following is a Ourvinvention relates to improvements in stereotyping outts, in which wecombine the operations of casting, sawing, shaving, and drying in onemachine. lVe accomplish this by the mechanism shown in the accompanyingdrawings, in which- Figure l is a side elevation, with large hand` c cleading to the cavity, and is known as theV steam-tableV or steam-box,B. Directly over this steambox is the press A, operated by the wheel a.In the central part of the table is the saw E, which can be lowered atpleasure below the table-surface .by the swinging arms h h, leaving thetable-surface clear for other use. The saw E is raised and lowered intouse by a lever formed by the continuation of one of theswinging arms h,and this lever is held inthe desired positions by a set-screw having aconvenient hand-wheel to turn it, thereby holding the lever and saw atwill.

The shaving-knife k is attached to two travel-l ing heads, F F, whichcarry shaft p, and in turn pinions Z and hand-wheel n. The racks m m aresecured by vbrackets to the table, and

are made to mesh into the pinions `Z l; hence 4 as the operator turnsthe hand-wheel n, the

'pinions must roll on the rack and carry the shaving-knife .7c back andforth, which is the movement necessary to shave stereotypeplates. Thecasting-box Gis journaled at f 4 in the adjustable arms d, which in turnare sustained by the pin d and lug e on the steambox or press end of thetable. These arms can be Ylowered by pulling them to the left till theslotted end no longer touches the lug e. Then it is revolved downwardabout the pin d. It is evident that several of the machines can bev usedtogether, or any one singly, and that the combined operations facilitatestereotyping both in utility and speed. The press and steam-table aregenerally used first. Directly afterward the stereotype is cast in thecasting box C. Then it is put on the table D and sawed and shaved. Theshavings are rolled up to the right and drop into the'box' o. Most 6 oi'the parts separately are not claimed or considered new, but the combinedoperations on one machine are believed to be both new and f useful.

We claim- 6 The combined stereotyping outfit composed and constructed ofthe main table D, having a slot for the saw E to be raised into use, ashaving-knife, F k, steam-box B, press A, and casting-bor; C, allarranged as shown and dej scribed.
